Question of the Day: Best recipient for supercharged GM V6?

The good old Buick V6 engine was built from 1961 through 2008 (including a decade of production by Kaiser-Jeep) and went into way too many General Motors vehicles to list here. In 1991, the supercharged version of the 3800 was introduced, with a Roots-style Eaton blower on top, and now you can find these engines in just about every junkyard in North America. The 3800 shares a bellhousing pattern with the also-made-by-the-zillions GM 60° V6 engine, which means that it will install (with varying levels of sledgehammer clearancing and/or axle mix-and-matching) into plenty of GM vehicles that never received the 3800 from the factory. That means one thing: engine swaps! An excellent example of this is the 1992 Chevrolet Lumina APV "Dustbuster" minivan, which is a fully caged high-performance road-racing machine that features a supercharged 3800 and 5-speed manual transmission under its long, vacuum-cleaner-snout-like hood. The RaceVan, in Springfield Monorail livery, will compete this weekend at the Michigan 24 Hours of LeMons race with Autobloggers Mike Austin, David Gluckman, and Alex Kierstein at the wheel. My personal choice for supercharged 3800 power, though, has to be the Cadillac Cimarron, preferably the not-so-sought-after Cimarron d'Oro Edition. Some bashing and welding and cutting and pasting and this lightweight Cavalier sibling could have well over double its original horsepower. So, what's your blown 3800 engine-swap choice?

GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

2017 Buick LaCrosse priced at $32,990

Buick has announced the starting price for its totally redesigned LaCrosse sedan, and it's looking competitive. According to the company's consumer website, the base trim will start at $32,990, while the vehicle featured on the page is helpfully listed as "As Shown: $45,560." Buick is being coy about the standard equipment list, but we do know a few traditionally higher-end options will be free of charge, including an eight-inch touchscreen that's compatible with Android Auto and Apple CarPlay, and HID headlamps. General Motors' 4G LTE wifi is a no-cost feature (although you'll need to shell out for a data plan, eventually). The optional extras list, which will include goodies like adaptive cruise control, hasn't been published yet. Underhood, all LaCrosse models will get eight-speed automatic transmissions paired with 305-horsepower, 3.6-liter V6 engines. The new powertrain, plucked from the Cadillac XT5, has stop-start and cylinder deactivation as standard to save fuel, although it's still too early to predict where the LaCrosse will fall on the EPA scale. Front-wheel drive is standard, but all-wheel drive will be available for a unknown premium. Buick says the sedan's reasonable starting price backs the company's "position of attainable luxury." And that's true. At $32,990 the LaCrosse is $560 less than the $33,550 base Toyota Avalon, $355 less than the $33,345 Nissan Maxima S, and $850 less than the $33,840 Kia Cadenza. Only the antiquated Ford Taurus, at $27,985, can undercut it. On the opposite end, the LaCrosse is $6,945 less than a front-drive Lincoln MKS and $6,060 less than a Lexus ES. Starting prices are useful tools for comparison but they only go so far – we'll have to wait until next month, when full details are released, to see how truly reasonable the LaCrosse's price is.
